Self-assembled monolayers made using sub-micron dielectric spheres are analogous to atomic monolayers that have proved to be a modern workhorse in condensed matter physics. Here, we discuss the origin of optical resonances associated with sub-micron dielectric monolayers through experiments that are further supported by theory and simulation. These resonances are used to enhance the emission rate of nitrogen-vacancy centers in nanodiamonds. Emission decay rate measurements confirm a 14% decrease in the excited state lifetime, which implies an enhanced emission rate at the resonances. The increase in measured decay rates is supported by the calculated local density of optical states. Our results provide a platform to tailor light transport and emission for applications in photonics and quantum technology using these monolayers.

使用亚微米介电球制成的自组装单层类似于原子单层，后者已被证明是凝聚态物理学中的现代主力。在这里，我们通过理论和模拟进一步支持的实验讨论了与亚微米介电单层相关的光学共振的起源。这些共振用于提高纳米金刚石中氮空位中心的发射率。发射衰减率测量证实激发态寿命减少了 14%，这意味着共振处的发射率提高。计算的局部光学状态密度支持测量衰减率的增加。我们的结果提供了一个平台，可以使用这些单层为光子学和量子技术中的应用定制光传输和发射。
